American motorists are bracing for further increases in gas pump prices this summer after average national prices rose 12 cents in the past week alone. AAA says drivers are experiencing "sticker shock" as increased summer demand, unrest in Egypt and production disruptions in the U.S. and other countries push up the price of crude oil and gasoline. The national average price for regular unleaded gasoline was $3.67 a gallon on Friday, July 19, 2013. (AP Photo/Seth Perlman, File)
